^I sort of agree with this, unfortunately. In my experience there is a lot of racism among Arabs—so the whole skin shade issue might come up. Not unlike desis as another poster said----mom and dad might be OK with you bringing home someone with lighter skin, but a darker shade can cause problems.
My comments are not specific to dating but just to overall characteristics I noted in my experience with Arabs. Also, my experience is with non-Gulfies. I think there’s a load of difference between Gulfies and non-Gulfies in terms of social attitudes, level of spoiledness, level of exposure/ability to interact with the opposite sex, expectations in terms of looks, material provision, etc., as others have noted. So everything I’ve observed comes from being around non-Gulf Arabs.
I don’t think that Arabs necessarily tend to be less religious, but in my experience they are less dogmatic and less superstitious than desis. Remember that conservative and religious are not exactly the same thing----IMO Arabs are just as religious but maybe tend to be less conservative. Perhaps because they have the advantage of Arabic as a first language, they also seem to be less preoccupied with observing every last detail of sunnah----please don’t take offense at this—I just feel like perhaps the ritualistic aspects of religion are not as essential to many Arabs because their greater understanding of the language of the Quran, hadith, etc., gives them a more organic relationship on some level with Islam. For example in a mostly desi mosque I used to go to, there were always Bengali guys going around to all of the brothers and making sure their pants were rolled up and giving them perfumed oil to put on; most Arab guys tend to not worry much about the outward etiquettes like hennah in the beard, sunnah-length pants, wear perfume to mosque, etc., yet they have pretty excellent understanding of the Quran.
Ideas of dressing/modesty are different between Arab and Pakistani women. I noticed Arab girls who wear headscarves tend to be very careful that none of their hair is showing and also tend to wear long sleeves all the time (a lot of desi girls will have some hair showing, or their dupatta slipping, and will wear half sleeves even with full hijab headscarf.) At the same time, however, many of them will wear shirts or pants that are tighter than what many desi women would consider acceptable. I’m used to dressing in a more Arab style (wearing hijab Arab style, at home wearing caftan), and when my husband first saw me wearing a caftan at home he told me his mom would be upset that I don’t have a dupatta across my chest. This surprised me because the dress is long, covering, and not too tight, and in an Arab home the women will typically find this very sufficient and not wear some sort of extra scarf, etc., to hide the contour of their boobs. So there would maybe some adjustment of expectations in a mixed Arab/Pakistani household of how the girls should dress most properly.
I find Arabs to be very fun-loving. If you are around Egyptians you’ll always be laughing—they love to joke. And Arabs from all countries are great dancers and love music. They also tend to be very affectionate and are very sensitive that you put a lot of time into maintaining your friendships or relationships with them. They also tend to be very expressive and outgoing, whereas I find that many Pakistanis are more reserved or shy. An Arab house is almost always a very loud, boisterous house. The downside is that people tend to have hotter tempers and will shout more, argue more, etc., than I’ve seen Pakistanis doing. Very Mediterranean in this sense, not unlike Italians, Greeks, etc.
I also find Arabs to be more frank in some ways than the Pakistanis I’ve been around. For example, even in more conservative families, when girls are with girls alone or boys with boys alone, people talk quite openly about sex, love, relationships, etc. Seems to be me that people have fewer taboos in talking about sex, pregnancy, marriage issues, etc. The girls in my husband’s family are extremely shy to talk about anything like this; even right as they are about to get married or newly-wed, they will never, ever, ask for any advice or questions about sex, love, keeping the relationship interesting, etc. I still remember a sister of my Palestinian roommate who was about to get married----she was a very good girl from a religious family, quite conservative. Her husband-to-be had purchased a home for them and furnished it, and he gave her the keys so that she could show it to us. Walking into their bedroom made me blush like crazy, but she wasn’t shy at all-----the color scheme was red, and there were mirrors everywhere—including one on the ceiling above the bed!!!
